This is the first book to cover the Holocene geology and geomorphology of the 9,200 kilometers of the Brazilian coast. It is written for third and fourth year undergraduates, post-graduate students, scientists and man- ers. It characterizes the Brazilian coast in terms of the Holocene geology, geomorphology, oceanographic and climatic conditions, and the location, morphology and evolution of the barrier types. Separate chapters outline the types of barriers and coastal dynamics in each state, beginning in the south and proceeding to the north. Some emphasis is placed on the stretches of coast where the detailed morphology and stratigraphy of b- riers has been previously determined. To date, the Brazilian coastal barriers have been largely ignored by the international community, partly perhaps because much of the past research has tended to concentrate on barrier islands, of which there are very few in Brazil. In contrast, the Brazilian coastal barriers display a much wider range of types than is generally assumed. The biggest and most spectacular transgressive dunefield barriers in the world exist in Brazil, and dominate the southern and northeastern coasts. Many have never been described - fore. This volume provides a wealth of information on Holocene barrier types, evolution and dynamics. It provides managers, ecologists, biologists and botanists with much needed information on the geology, geomorph- ogy and dynamics of the genesis, types, functioning and ecosystems of the Holocene barriers extending along the entire Brazilian coast.

This Brief provides a comprehensive overview of Trypanosoma cruzi, a parasite that is traditionally considered as exclusively vectorborne, but can be foodborne, and may lead to outbreaks of Chagas disease in consumers. The characteristics of Trypanosoma cruzi and the clinical effects of the disease are covered, including documented outbreaks, regional patterns, and epidemiology. The various transmission routes are outlined, but with specific focus on foodborne transmission. A major emphasis of this text is contamination of fruit juices with Trypanosoma cruzi in, a transmission vehicle with increasing significance in the spread of this parasite. Also outlined is the difficulty of establishing a protocol for detection in food samples. Results on survival of Trypanosoma cruzi in food matrices is considered, as well as current risk assessment procedures and regulations. Different approaches to preventing transmission, including inactivation and decontamination are introduced, but also the importance of targeted educational initiatives, and also with a focus on future detection, prevention, and prevention of contamination of foods with this parasite.

Neotropical forests sustain a wealth of biodiversity, provide a wide range of ecosystem services and products, and support the livelihoods of millions of people. But is forest management a viable conservation strategy in the tropics? Supporters of sustainable forest management have promoted it as a solution to problems of both biodiversity protection and economic stagnation. Detractors insist that any conservation strategy short of fully protected status is a waste of resources and that forest management actually hastens deforestation. By focusing on a set of critical issues and case studies, this book explores the territory between these positions, highlighting the major factors that contribute to or detract from the chances of achieving forest conservation through sustainable management.
